A sustainable use of soil resources is urgently required to cope with the increasing demand for agricultural products during climate change. To inspire farmers on new soil cultivation methods like subsoil management requires not only yield measurements but also nutrient use efficiency measurements f…

In agriculture, efforts are being made to reduce pesticides and fertilizers because of the possible negative environmental impacts, high costs, political requirements, and declining social acceptance. With precision farming, significant savings can be achieved by the site-specific application of fer…

Hernández-Ochoa I., Gaiser T., Kersebaum K., Webber H., Seidel S., Grahmann K., Ewert F. (2022.0). Model-based design of crop diversification through new field arrangements in spatially heterogeneous landscapes. A review. Agronomy for Sustainable Development, 42(4), . doi:10.1007/s13593-022-00805-4

AbstractIntensive agriculture in Germany is not only highly productive but has also led to detrimental effects in the environment. Crop diversification together with new field arrangements considering soil heterogeneities can be an alternative to improve resource use efficiency (RUE), ecosystem serv…

Seidel S., Gaiser T., Srivastava A., Leitner D., Schmittmann O., Athmann M., Kautz T., Guigue J., Ewert F., Schnepf A. (2022.0). Simulating Root Growth as a Function of Soil Strength and Yield With a Field-Scale Crop Model Coupled With a 3D Architectural Root Model. Frontiers in Plant Science, 13(), . doi:10.3389/fpls.2022.865188

Accurate prediction of root growth and related resource uptake is crucial to accurately simulate crop growth especially under unfavorable environmental conditions. We coupled a 1D field-scale crop-soil model running in the SIMPLACE modeling framework with the 3D architectural root model CRootbox on …

Cropping system diversification through annual intercropping provides a pathway for agricultural production with reduced inputs of fertilizer and pesticides. While several studies have shown that intercrop performance depends on the genotypes used, the available evidence has not been synthesized in …

Nguyen T., Langensiepen M., Hueging H., Gaiser T., Seidel S., Ewert F. (2022.0). Expansion and evaluation of two coupled root–shoot models in simulating CO ₂ and H ₂ O fluxes and growth of maize. Vadose Zone Journal, (), . doi:10.1002/vzj2.20181

Leaf water pressure head (Ψleaf) and more specifically its critical thresholds (Ψthreshold) characterize stomatal control of transpiration, particularly for C4 plants, but this physiological process has rarely been integrated into dynamic crop models at the field scale. We further extended two coupl…

Khare D., Selzner T., Leitner D., Vanderborght J., Vereecken H., Schnepf A. (2022.0). Root System Scale Models Significantly Overestimate Root Water Uptake at Drying Soil Conditions. Frontiers in Plant Science, 13(), . doi:10.3389/fpls.2022.798741

Soil hydraulic conductivity (ksoil) drops significantly in dry soils, resulting in steep soil water potential gradients (ψs) near plant roots during water uptake. Coarse soil grid resolutions in root system scale (RSS) models of root water uptake (RWU) generally do not spatially resolve this gradien…

Abdalla K., Sun Y., Zarebanadkouki M., Gaiser T., Seidel S., Pausch J. (2022.0). Long-term continuous farmyard manure application increases soil carbon when combined with mineral fertilizers due to lower priming effects. Geoderma, 428(), 116216. doi:10.1016/j.geoderma.2022.116216

Organic and synthetic fertilizers not only increase soil fertility and crop productivity but also enhance soil organic carbon (SOC). However, the priming effect (PE) leads to increased soil carbon (C) loss through native SOC mineralization. To date, the mechanisms by which long-term (>66 years) synt…
